About The Position

The Software Department team in Atlanta, GA is seeking a highly motivated, experienced Principal Embedded Software Engineer to be part of their team supporting Electronic Warfare (EW) programs. This role requires deep expertise in embedded software, SoC architectures, and FPGA‑integrated systems, as well as the ability to translate system‑level requirements into robust, deterministic software implementations. The position is located onsite in Atlanta, GA.

Requirements

Typically requires a Bachelor’s in Science, Technology, Engineering or Mathematics (STEM) and a minimum of 8 years of prior relevant experience.
Experience with programming languages such as C/C++ and Python for automation, integration, build tooling, and verification workflows.
Experience building deterministic real‑time software on bare‑metal and embedded Linux (Yocto), including kernel configuration, bootloader (U‑Boot) modification, and driver development OR similar.
Experience debugging of system boot flows, memory initialization, transceiver bring‑up, kernel modules, and user‑space interactions.
The ability to obtain and maintain a U.S. government issued security clearance is required.
U.S. citizenship is required, as only U.S. citizens are eligible for a security clearance.

Nice To Haves

Active Secret security clearance.
Experience developing on ARM‑based SoCs with integrated FPGA fabric, including AXI‑based interfaces, DMA engines, DDR subsystems, and SPI/I2C/UART peripheral architectures.
Experience working on Electronic Warfare (EA/ES), radar processing chains, or secure communications architectures.
Experience with .NET C#, WPF/MVVM, Visual Studio, Vitis, Jenkins, Jira, Collaborator, and TortoiseSVN.
Extensive lab experience with advanced instrumentation (high‑speed oscilloscopes, vector signal generators, logic analyzers) and SoC/FPGA debug interfaces (JTAG, trace analyzers).
Familiarity with bus architectures such as VME, VPX, PCI/PCIe, and Gigabit Ethernet.
Experience across the full software engineering lifecycle including architecture definition, requirement decomposition, code generation, unit/functional testing, and system-level validation.
Background in signal processing, radar algorithms, low‑level optimization, or hardware‑accelerated compute architectures.
Experience with RTOS environments, real‑time schedulers, and deterministic task execution.
Knowledge of networking protocols, low‑level packet handling, and embedded communication stacks.

Responsibilities

Derive embedded software and FPGA interface requirements from high‑level system specifications and CONOPS.
Architect, implement, and integrate embedded C/C++ software for ARM‑based SoCs, microprocessors, and FPGA‑coupled processing pipelines.
Develop software–firmware interaction layers, including register‑level interfaces, low‑level drivers, memory controllers, and high‑speed serial transceiver integrations.
Perform system modeling, timing analysis, and simulation of embedded execution paths and data flows.
Develop and debug real‑time applications on bare‑metal and embedded Linux platforms, including custom Yocto‑based distributions.
Execute board‑level bring‑up, bootloader configuration, device‑tree tuning, and BSP customization for SoC platforms.
Debug complex system interactions involving DDR, flash, multi‑gigabit transceivers, synchronization signals, power‑on sequences, and RF‑connected electronics.
Perform in‑lab testing and characterization using logic analyzers, high‑speed oscilloscopes, protocol analyzers, and FPGA/SoC debugging tools.
Conduct root‑cause analysis of system‑level software failures, Linux kernel issues, and FPGA‑software integration defects.
Collaborate closely with systems, FPGA, RF, and electrical engineering teams to ensure interface compatibility, timing closure, and system performance margins.
